  • Sun to part shade. Reportedly resistant to Dutch elm disease and elm yellows; good resistance to elm leaf beetle.
  • Hardy to USDA Zone 4       Triumph™ (cultivar name ‘Morton Glossy’, initially named 'Charisma' until it was realized in 1995 the name was already in use) resulted from a controlled cross conducted by Dr. George Ware at The Morton Arboretum between Vanguard™ Elm (Ulmus pumila x Ulmus japonica) and Accolade® Elm (Ulmus japonica x Ulmus wilsoniana).  In the Flora of China, Ulmus japonica is now classified as Ulmus davidiana var. japonica and Ulmus wilsoniana as Ulmus davidiana var. davidiana.
